WOVEN- WIRE MATTRESS.

SPECIFICATION forming part of Letters Patent No. 446,193, dated February10, 1891.

Application filed November 24:, 1888. Serial N0. 291,745- (No model.)

To all whom it may concern.-

Be it known that- I, \VILLIAM S. SEYMOUR, a citizen of the UnitedStates, residing in the city of Philadelphia, county of Philadelphia,

State of Pennsylvania, have invented certain new and useful Improvementsin Woven- Vire Mattresses, of which the following is a specification.

In Letters Patent of the United States [0 granted to me September188%),No. 410,937,

and which in part constitute a division hereof, is shown and claimed awoven-wire mattress made up of an upper and a lower wovenwire fabricwith intermediate springs, whose 1 terminal coils are connected theretoin such away that the tendency of said coils to expand keeps the fabrictaut. The preferred means for attaining the desired result is shown tobe through the instrumentality of parallel extra wire cables intertwinedwith the fabric and arranged at a distance from each other less than thediameter of the said terminal coils, so that by compressing the top andbottom coils of each spring and running said coils through two adjacentwire cables each cable is maintained at a uniform distance fromthe-adjacent parallel cable, the cables are kept in position below thesurface of the woven-wire fabric, and the fabric pre- 0 sents a uniformouter surface, which is maintained taut by reason of the tendency of thecompressed terminal coils to expand.

The present invention is embodied in a construction possessing the samefeatures of 5 advantage, with the additional characteristic that thewoven-wire fabric is carried around and joined at its ends, so as toinclose or envelope the assemblage of springs at top, bottom,and sides.By sides I mean those portions of the mattress between its top andbottom edges where the folding of the fabric takes place. I employ theterm gewire fabric which is carried around them at top, bottom, andsides,,the terminal coils of the springs engaging with the fabric at topand bottom.

In the accompanying drawings, Figure 1 represents a spring bed-bottom ormattress embodying my invention. Fig. 2 represents aplan View of aportion of the same, and Fig. 3 represents a section taken on the line GG of Fig. 2.

Similar letters of reference indicate similar parts throughout theseveral views.

As shown in the drawings, the mattress or bed-bottom consists of awoven-wire fabric A, forming its top and bottom and connected byintermediate perpendicular spiral springs B, as shown, said fabric beingcarried over the sides of the assemblage of springs and joined at itsends, so as to encompass the same.

The mattress is, for convenience, made in two sections, so as to bereadily shipped or stored. The springs are connected at their oppositeends to the fabric by means of the extra or auxiliary wires or cablesF,'intertwined within the coils of the fabric. The upper and lower loopsor terminal coils E of the springs B are first compressed and in thecompressed conditioninsert-ed between adjacent cables. The tendency ofthe said coils or loops to expand stretches the fabric, and at the sametime the extra wire cables F are drawn in, so as to leave the surface ofthe woven wire fabric without .any projecting obstruction. It will beevident that with the construction shown the spring bed-bottom ormattress will be reversible, so that either surface may be uppermostwhen the niattress is in use.

What I claim is A woven-wire mattress consisting of an assemblage ofperpendicular springs and a wm en-wire fabric covering the top, bottom,and sides of said springs, the terminal coils of the springs engagingwith the fabric at top and bottom, substantially as described.
